Overview
WindowGOOP® Original is a water-based acrylic co-polymer emulsion that goes on as a viscous milky-white liquid and dries to a translucent clear film. It protects glass surfaces from dirt, paint, scratches, welding flecks, cement and other site damage, while still letting 82–89% of visible light into the building.
When the work is complete, just peel it off or jet-spray it away. A self-cleaning additive keeps the glass clean underneath, so there is no unsightly residue at handover. It contains no corrosive additives and is compatible with most glass types tested, including Low-E, hard-coated and soft-coated glass.
Protects glass on site
Takes mortar, render, paint overspray, welding flecks and cement slurry so the glass doesn’t.
Keeps the site naturally lit
The dried film is translucent, transmitting 82–89% of visible light.
Peels away clean
Peel by hand or jet-spray off at handover. No scrubbing, no harsh cleaners.

How to apply
Apply
Roll on one even coat to at least 100 µm dry film. Go above 150 µm on aluminium joinery and horizontal surfaces such as benchtops, or for long, abrasive programmes. Apply at 5–35 °C, RH below 85%, with no rain due.
Protect
Touch-dry in 20–60 minutes at 25 °C. Rated for 12 months outdoors at 100 µm and 12–24 months at 150 µm in average conditions. If soaked it may turn white, then dries back to its normal look.
Peel
Peel it off by hand or jet-spray it away at 0–50 °C. In cold weather, warm water helps release; in extreme heat, use cold tap water.

Frequently asked questions
How long can WindowGOOP Original stay on the glass?
In average conditions, a 100 µm dry film is rated for 12 months of external exposure and a 150 µm film for 12–24 months. Extreme environments can shorten this.
How do I remove it?
Peel it off by hand or jet-spray it off. It can be removed between 0 and 50 °C. In cold weather warm water helps release; in extreme heat use cold tap water.
Which glass can it be used on?
It is recommended for float, clear-tinted, Low-E and hard-coated glass, and was found compatible with most glass types tested, including soft-coated glass. It contains no corrosive additives.
Can it be used on aluminium or PVC frames?
It may be used on powder-coated and anodised aluminium and on PVC joinery, but a test trial is strongly recommended. Apply above 150 µm dry film on aluminium. It is not suitable for acrylic sheet or Perspex.
Will it leave residue on the glass?
No. A self-cleaning additive keeps the protected surface clean during construction, so it peels away without unsightly, hard-to-remove residue.
What happens if it rains?
Avoid applying when rain is imminent. Once cured, a soaked film may turn white and will dry back to its original appearance; the longer it cures, the better it performs when waterlogged.
